Write out the research hypothesis (name the variables and say they are related) and the null hypothesis (name the variables and say that they are not related).

  • Figure the df (total N-2) and, using an alpha of 0.05, find the critical value of t.( Scanned file)
  • Make a decision about the null hypothesis – accept or reject.
  • Interpret your findings – is there a relationship between these two variables? If so, what is the nature of that relationship? (Refer to the means…) Speculate on why these findings might be as they are.
